[Trilinos-Users] Linking problems with LOCA and Anasazi

[Jonas Thies]

Hi all,

I encounter a problem when trying to use loca and anasazi independently 
in the same program. More specifically, the loca headers are included in 
the .C file with the main() routine. In another .C file, which I want to 
link to later, I recently added the line

#include "AnasaziBlockKrylovSchurSolMgr.hpp"

whereupon the linker produced the error at the end of this message.
It looks like some templates are instantiated twice, what can I do to 
avoid this?
Thanks,
Jonas
